NASA's Orion spacecraft - the heat shield must be capable of withstanding the intense pressures of re-entry into Earth's atmosphere at roughly 20,000 mph (32,187 km/h), and to withstand temperatures exceeding 4,000 ºF (2,204 ºC). The five-meter (16-ft) wide heat shield for the crew module of the Orion spacecraft, is comprised of silica fibers with an epoxy-novalic resin filled in a fiberglass-phenolic honeycomb.
